kardiomyocyterna
Kardiomyocyterna, also known as cardiac muscle cells or cardiomyocytes, are specialized cells responsible for the contractile function of the heart. These cells form the muscular tissue of the myocardium, the heart's main muscular layer, and are essential for enabling the rhythmic contractions necessary for blood circulation.
Structurally, cardiomyocytes are elongated, cylindrical cells with a centrally located nucleus, although some may contain multiple
Cardiomyocytes contain specialized contractile proteins, primarily actin and myosin, organized into sarcomeres—the fundamental units of muscle
The development of cardiomyocytes occurs primarily during embryogenesis, originating from mesodermal progenitors. Most adult cardiomyocytes are
Pathological conditions affecting cardiomyocytes include hypertrophy, hypertrophic cardiomyopathy, and various forms of cardiomyopathy, which can impair
